Abstract (en)
[origin: US2005151755A1] Three values for each CAD image element are set: an element priority, a level priority, and a model reference priority. In addition, for the CAD project that contains the CAD image element, a separate priority multiplier value may be set project-wide for elements, levels, and models, creating an element priority multiplier, a level priority multiplier, and a model reference priority multiplier. Once the priority values and priority multiplier values have been set, either by default values or by the user, the values are used to calculate an image depth for each CAD image element. The image depth values are stored, for example in a z-buffer, and can be used to set the display priority for the CAD image elements regardless of the order in which they are placed into the image.
